The Solomon Islands opposition says it has not had any discussions with ten PMs who are reported to be planning to cross the floor.
The ten are affiliates of the Association of Independent Members and include government ministers.
An opposition source, who did not want to be named, says although they haven't had any talks, they won't rule them out, and they are observing the situation with interest.
He says the ten would probably be welcomed on to the opposition benches where there are 11 opposition MPs, and a separate group of independents of 5 MPs.
He says this could lead to the opposition being able to count on 26 MPs in the 50-seat house, which is down to 48 MPs after Daniel Fa'afuna was jailed and Nathaniel Waena was elected the governor-general.
The prime minister, Sir Allen Kemakeza, has left on a trip to Papua New Guinea and then Samoa for the Pacific Islands Forum meeting.
